Ah, but are you hearing the noise, or a recording of the noise? And is not the frequency analyzer detecting the vibrations, and not actually hearing the noise? "Measurable effect" also falls in the realm of science. It does not work with the idea that noise is only that which is heard by someone or something that can speak about it- i.e. an intellegent being. This is outside of the scientific pathway, and onto another. It crosses onto the "Cogito Ergo Sum" idea created by Descartes.
